VALQVE OR FAUCET.

' SPECIFICATION forming part of Letters Patent No. 589,102, dated August31, 1897.

Application filed August 20,1896. Serial No. 603,285. (No model.)

To all whom it may concern:

" Be it known that I, LEO SIMMONS, a citizen of the United States,residing at Vashing'ton, in the District of Columbia, have inventedcertain new and useful Improvements in Valves or Faucets; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to cocks or faucets,

and more particularly to improvements in that class of faucets known asstraightway valves, which have two openings in the valvecasing,with acorresponding number of valves for closing said openings.

It is the purpose of this .invention to provide a non-frictional valveof this class which will be perfectly tight or close fitting, so as toprevent any leakage of water or other fluid when shut off, and will bedurable and not easily worn out. w

' It is a further purpose of my invention to provide a valve which issimple in construction, easy in operation, and comparatively inexpensiveto manufacture.

Briefly the invention consists of a valvecasing havinga wedge-shapedvalve-seat and a correspondingly-shaped valve consisting of a pair ofval e faces or wings hinged directly together at their lower ends andconnected at their upper ends to a vertically-movable spindle by meansof links, the valve as thus constructed being of wedge shape to fit thecorrespondingly-shaped seat in the casing.

To these ends the invention consists in the novel features ofconstruction and new combinations of parts hereinafter more fullydescribed, and particularly pointed out in the claims which follow thisspecification.

-In order to enable others skilled in the art to make, use, andconstruct my invention, I will now proceed to describe the same indetail, reference being had to the accompanying sheet of drawings,wherein- Figure 1 is a longitudinal view of a valve constructedaccording to myinvention. Fig. 2 is a plan view of the valve-casing withthe valve removed and Fig. 3 is a detail perspective view of the valveproper, the parts being disconnected.

Referring now to the drawings, the reference-numeral l designates thevalve-casing, which may be of any desired form and providedwith an inletand outlet opening and with, acentral valve-chamber 2. The valvechamberis formed at its lower portion by inclinjed side walls 3 3, whichconstitute awedgeshaped valve-seat, and in the center of these sidewallsare arranged the liquid-passages 4 5,,which are substantially oppositeeach other. Extending upward from the valvecasin g is the valve-domedwhich is provided with screw-threads upon its interior and exterior,those upon the interior being preferably larger and extending over theentire inner surface of, the dome. A cap 7 is screwed upon the topof thevalve-dome and is provided with a central aperture 8, through which thevalve-spindle passes, and is also preferably provided with. astuffing-box 9, of

any suitable construction, so as to insure against leakage at theseparts.

The reference-numeral 10 designates my improved valve, which consists ofa pair of wings or plates 12 13, that are formed at their upper andlower ends with apertured ears 12' '13, as shown, the lower ones ofwhich interlock and are pivoted together in any suitable manner. Betweenthe cars at the upper ends of the plates or wings are loosely orpivotally connected the links 14, which in turn are pivoted betweendownwardly-extending ears 15,

formed on a head 15. This head is swiveledto the lower end of thevalve-operating spindle 16 by means of a screw or other fastening device17., which is passed loosely through an aperture in the head and intothe end of the spindle. Secured directly to the lower portion of thespindle is a circular disk or body 18, which isexteriorlyscrew-threaded, so as to engage with the threads Within the valvedome.It will now be readily seen that by turning the vhandle 19, which issecured to the spindle, the circular disk or body 18 will be raised orlowered, according to the direction the handle isturned, and the valvewill be accordingly raised or pressed to its seat.

It is to be noted that the lower down the In raising the valve from itsseat the spindle in being screwed upward first draws the valve-platestogether away from the valveseat and then raises the valve. By thisoperation it will be seen that there is no friction between the valveand valve-seat during the opening and closing of the valve. To the outerface of each valve plate or wing is secured a rubber or leatherpacking-strip 20, as shown in Fig. l of the drawings, which will insurea tight seating of the valve.

111 order to prevent the links from being pressed down too far, whichmight result in straining their connections, I have formed anoutwardly-projecting lug 21 upon the inner face of each valve-platedirectly below the links, so that as soon as the valve is opened out toits greatest width the links will strike against the lugs or stops andfurther downward movement of the same will be prevented and thestraining of the parts avoided.

Arranged within the interior of the valvecasing,longitudinally with thesame, I have provided a pair of guide rods or bars 22, one upon eachside of the valve-opcnin gs. These rods serve to keep the valve-platesperfectly true and in a correct position for the proper seating of thevalve-plates and also prevent any sidewise orlateral movement of thevalve.

It will be seen from the foregoing description that I provide a valvethat can be quickly and tightly forced to its seat and as easily openedto allow the How of liquid, and owing to the fact that the valve andseat are each of wedge shape a much better and safer water seal iseflected; and, further, the parts are so constructed and arranged thatthe valve can be readily taken apart for inspection, cleaning, orrepair.

I do not wish to be understood as confining myself to any particularform orconstruction of valve-casing, as any form will answer the purposeof this invention, the essential fea- \Vhat I claim, and desire tosecure by Letters Patent, is

1. In a valve, the combination with the valve-casin g provided with aV-shaped valveseat, of a V-shaped valve consisting of apair of plateshinged together at their lower ends, an operating device for moving thevalve to and from its seat, a linked connection between the valve andoperating device, and stop-lugs on the valve-plates directly below thelinks for limiting the downward movement of the latter, substantially asdescribed.

2. In a valve, the combination with the valve-casing provided with aV-shaped valveseat, of a V-shaped valve consisting of a pair of plateshinged together at theirlower ends, an operating device for the valve,links connecting the valve-plates and operating device, and guide-rodssecured to and spanning the walls of the valve-seat and acting on eachside of the valve plates, substantially as described.

3. In a valve having a V-shaped valve-seat, aV-shaped valve consistingof a pair of plates hinged together at their lower ends and having alinked connection at their upper ends with an operating device formoving the valve to and from its seat, stop-lugs on the valveplatesdirectly below the links, and guiderods secured to and spanning thewalls forming the valve-seat, said rods acting on each side of thevalve-plates, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

LEO SIMMONS.
